7f42d63687 Bugfix: ota fails with secure boot on for image size greater than 3.2MB
When an OTA image size is larger than 50 MMU pages (approx. 3.2 MB), secure_boot_generate fails while trying to map it into memory:

https://github.com/espressif/esp-idf/blob/master/components/bootloader_support/src/esp32/secure_boot.c#L72
Instead of trying to map the whole image, secure boot code should split the image into chunks and map them one by one, like it is done in esp_image_format.c:

b1ee25afde bootloader: account for load address when mapping cache pages
Bootloader used to calculate the number of cache pages assuming that
load address was aligned, while in reality load address for DROM and
IROM was offset by 0x20 bytes from the start of 64kB page. This
caused the bootloader to map one less page if the size of the image
was 0x4..0x1c less than a multiple of 64kB.

Old rationale for "priv" no longer applies.
